If your bowel movement smells like sulfur or eggs and you have diarrhea, what does it mean Children in diapers and people with diarrhea may accidentally contaminate pools and spas. It is also possible to swallow giardia from surfaces such as bathroom handles, changing tables, diaper pails, or toys that contain feces (poop) from an infected person or animal. Because cooking food kills giardia, food is a less common source of infection than water. Often occurs in pregnancy from the pressure of the growing baby or right after childbirth from the pressure from pushing. Just because you get gas from certain foods does not necessarily mean your baby will. Gas is created way down in our large intestines when the healthy bacteria in our gut breaks down the undigested carbohydrates (sugar, starches, soluble fiber).

A wide variety of disease processes V and conditions can cause these signs, and the underlying condition may be mild and self-limiting or severe and life threatening. The uid and electrolyte losses from vomiting and diarrhea can contribute to morbidity and mortality associated with the underlying condition. Additionally, septic complications can result from aspiration pneumonia associated with vomiting and bacterial translocation associated with some types of diarrhea. This article focuses on the pathophysiology and treatment of hypovolemia, dehydration, electrolyte disturbances, and acid-base derangements resulting from and associated with vomiting and diarrhea. It is a coordinated process involving multiple afferent and efferent neurologic pathways. Coordination of vomiting occurs at the level of the medulla oblongata of the hindbrain [1]. Sensory vagal Peripheral sensory bers are predominantly vagal, with glossopharyngeal (oro pharynx) and sympathetic (urogenital) bers also contributing. Chemoreceptors in the area postrema are func tionally outside of the blood-brain barrier and are sensitive to circulating emetic agents [4]. Detection of circulating toxins causes a reex action to expel these ingested toxins, and this reex represents a long-preserved evolutionary sur vival technique for many species. Animals with vestibular disorders can have persistent vomiting that may lead to clinical con sequences of hypovolemia, dehydration, and electrolyte disturbances. If bal ance, mentation, or other cranial nerves also are compromised in these animals, they may be unable to protect their airway, and thus be at increased risk for aspiration during vomiting. The coor dinated contraction of abdominal muscles and relaxation of the gastric cardia then occur by means of the dorsal vagal complex (Fig. Diarrhea Diarrhea is an increase in fecal volume caused by an increase in fecal water [5]. Pathophysiologic mechanisms include increased intestinal secretion; decreased intestinal absorption; decreased transit time; and mesenteric, vascular, or lym phatic disease [6]. Damage to the intestinal epithelial barrier may lead to decreased absorptive capacity. When the absorp tive capacity of the intestines is overwhelmed, osmotically active molecules retain water in the intestinal lumen, resulting in excessive fecal water loss (ie, osmotic diarrhea). An increase in intestinal osmolality and resultant osmotic diarrhea also may occur after dietary indiscretion or lactulose administration. Bacterial enterotoxins, unconjugated bile acids, and hydroxylated fatty acids all stimulate intestinal secretion. Diagnostically, diarrhea is commonly characterized as small or large-bowel diarrhea. Fluid and electrolyte loss can be extensive in patients with acute or peracute small-bowel diarrhea. Clinical signs of dehydration can be subtle, and the ability to detect dehydration based on physical examination depends on the age and nutritional status of the animal, acuteness of onset of the vomit ing or diarrhea, and any prior treatment. Typical clinical signs result from a loss of interstitial uid, leading to a loss of tissue pliability and lubrication. Clinicians must consider body condi tion score and age when assessing skin tent; subcutaneous fat provides greater lubrication than lean tissue. Consequently, the top of the head and axillary region rather than the more commonly evaluated dorsal cervical region may provide more information about hydration status. When the eye of a normal cat is retropulsed, the nictitans should immediately slip back into place after re lease of the eye. Evaluation of this variable is most valuable when normal body weight can be documented on the same scale before the onset of uid loss. Dehydration in dogs with vomiting and diarrhea results from isotonic or hypertonic uid loss and may be evident in changes to blood constituents. This difference is important to remember when assessing dehydration in puppies and kittens. Animals with incessant vomiting and diarrhea become progressively more dehydrated and eventually lose sufcient volumes of uid so as to develop a clinically relevant decrease in circulating blood volume. Hypovolemia Fluid loss with vomiting and diarrhea may lead to hypovolemia and compro mised perfusion of organs and tissues. Hypovolemic shock is one of the most life-threatening consequences of vomiting and diarrhea. Activation of normal physiologic responses protects against impaired tissue perfusion associated with hypovolemia. First, dietary sodium intake and water intake normally are greater than basal needs, and, second, the kidney is able to enhance sodium and water reabsorption to expand circulating volume [9]. Hypovolemia is the result of such severe volume loss that uid shifts and renal compensatory responses are unable to maintain circulating blood volume. Relatively large volumes of uid must be lost, or the rate of loss must exceed the potential for compensatory responses, before a patient becomes hypovolemic. Red blood cell volume may be decreased in some animals with vomiting or diarrhea associ ated with gastric ulcers or a bleeding disorder. Diseases that lead to systemic vasodilatation result in signs of shock with lim ited uid loss. This decreased venous pressure translates to a reduction in preload (end-diastolic volume) and inability of the heart to eject a normal stroke volume. The reex response to a decrease in stroke volume is to increase heart rate, and therefore restore cardiac output. Another compensatory response is peripheral vasoconstriction that manifests clinically as pale mucous membranes with prolonged capillary rell time, depressed mentation, cold extremities, and, frequently, low rectal temperature. Decreased delivery of oxygen to tissues secondary to hypovolemia results in anaerobic metabolism. The production of lactate by hypoperfused tissues results in a high anion gap metabolic acidosis. Lactate concentration can be measured by point-of-care analyzers, and therefore may be used as a marker of decreased tissue perfusion caused by vomiting or diarrhea. Electrolyte Disorders Electrolyte disorders are common in patients with vomiting, diarrhea, or both. Loss of these electrolytes by vomiting or malabsorption can thus lead to severe electrolyte abnormalities. Gastric contents contain high concentrations of sodium and chloride, and hyponatremia and hypochloremia commonly result from loss of these uids. The typical ndings of hyponatremia and hypochloremia are most common when only gastric contents are lost. If biliary secretions also are present in the vomitus, electrolyte changes are less predictable. Hypotonic uid loss may occur with osmotic diarrhea (eg, secondary to lactulose administration), however, resulting in hypernatremic dehydration [11]. The concentration of potassium in canine gastric secretions ranges from 10 to 20 mEq/L, increasing with increased rates of secretion [12]. Normal feces contain a high concentration of potassium, and protracted diarrhea may lead to severe fecal potassium loss [13]. For example, patients with vomiting and diarrhea attributable to hypoadrenocorticism typi cally are hyperkalemic as a consequence of mineralocorticoid deciency. Elec trolyte abnormalities depend on the underlying disease process causing the vomiting and are covered in more detail in the specic conditions discussed next. Although lactic acidosis may be assumed in the hypoperfused dog with vomit ing and diarrhea, acid-base status cannot be predicted from history and phys ical examination only. Patients with vomiting of gas tric origin typically have metabolic alkalosis because of loss of chloride and pro ton-rich uid and retention of bicarbonate by the kidneys. Bicarbonate secretion increases and chloride secretion 3A decreases with an increased rate of pancreatic secretion [15]. Patients with vomiting, diarrhea, or both may have an increase in blood lac tate concentration as a consequence of hypoperfusion. Lactic acidosis may be suspected based on clinical signs consistent with hypoperfusion or may be detected in whole blood using a point-of-care analyzer. Animals may be presented with mild dehydration or may be profoundly hypo volemic. Patients may have a normal electrolyte and acid-base status or have life-threatening abnormalities. Each animal must therefore be considered indi vidually, with careful attention paid to physical examination in addition to elec trolyte and acid-base status. Animals with vomiting and diarrhea typically have isotonic or hypertonic uid loss. Replace ment isotonic uids provide sodium and water; as such, they correct volume and hydration decits. Maintenance solutions contain a lower concentration of sodium, and therefore do not correct the volume and hydration decits in animals with vomiting and diarrhea. Different crystalloid solutions have different concentrations of electrolytes and different buffers (Table 2). Oral administration has the advantage of being the most physiologic route in addition to being economic and safe. Large volumes of nonsterile uids, electrolytes, drugs, and nutrition can be administered orally. The animal may voluntarily drink the uids, or an enteral feeding tube can be placed. Subcutaneous Isotonic crystalloid solutions can be administered subcutanously to treat mild dehydration in animals with vomiting and diarrhea. Patient selection includes patients that cannot be hospitalized and animals with self-limiting conditions that are likely to benet from rehydration. Hypertonic and hypotonic crystalloids, colloids, and dextrose containing solutions should not be given subcutanously. Skin necrosis may occur if uids are given subcutanously to a vasoconstricted, hypovolemic, or immunocompromised patient. Septic necrosis of the skin and abscessation may occur if dextrose-containing uids are administered. Intravenous Intravenous uid administration should be used to correct hypovolemia and moderate to severe dehydration because it allows precise titration of uids to meet uid requirements. Crystalloids (isotonic, hypertonic, and hypotonic), colloids, and blood products all can be administered intravenously. Intraosseous Intraosseous access is useful in patients that require rapid uid and drug admin istration when intravenous access is not possible. Intravenous catheterization in the hypovolemic puppy or kitten with vomiting and diarrhea may be techni cally challenging, and provision of isotonic crystalloids and dextrose by means of the intraosseous route may be life-saving. Correction of interstitial uid decits should begin during uid resuscitation for hypovolemia.

A formal decolonisation regimen medications causing hair loss buy cheap oxybutynin 2.5mg on line, using topical antibiotic and antiseptic techniques 911 treatment center order oxybutynin 5 mg, is not necessary for all patients medicine youkai watch oxybutynin 2.5mg free shipping, but may be appropriate for those with recurrent staphylococcal abscesses medicine bow national forest buy oxybutynin 5 mg with visa. Decolonisation should only begin after acute infection has been treated and has resolved symptoms uterine cancer order discount oxybutynin line. As part of the decolonisation treatment treatment hyperkalemia discount 2.5mg oxybutynin free shipping, the patient should be advised to shower or bathe for one week using an antiseptic. For a diluted bleach bath, add 1 mL of plain unscented 5% bleach per 1 L of bathwater (or 2 mL of 2. Alternatively, patients may shower daily for one week using triclosan 1% or chlorhexidine 4% body wash, applied with a clean cloth (and preferably left on the skin for at least fve minutes), particularly focusing on the axillae, groin and perineum. Clothing, towels, facecloths, sheets and other linen in the household should be washed then dried on a hot cycle in a clothes dryer, or dried then ironed, at least twice within the one week decolonisation period. Ideally, the household should also replace toothbrushes, razors, roll on deodorants and skin products. Hair brushes, combs, nail fles, nail clippers can be washed in hot water or a dishwasher. Surfaces that are touched frequently, such as door handles, toilet seats and taps, should be wiped daily, using a disinfectant. Bleach baths or antiseptic washing can be carried out intermittently after the initial decolonisation period, to help prevent recurrence of infection. This can also be recommended for patients with recurrent skin infections who have not undergone formal decolonisation. Antibiotic treatment Recurrent skin infections First choice Fusidic acid 2% cream or ointment (if isolate sensitive to fusidic acid) Mupirocin 2% ointment (if isolate resistant to fusidic acid and sensitive to mupirocin) Apply inside the nostrils with a cotton bud or fnger, twice daily, for fve days N. Antibiotics have little impact on the duration and severity of symptoms but eradicate stool carriage. Treatment is indicated for severe or prolonged infection, for pregnant women nearing term and for people who are immunocompromised. Treatment may also be appropriate for food handlers, childcare workers and those caring for immunocompromised patients.

Dose is per 3 kg bodyweight; ornidazole is only available in tablet form, tablets may be crushed, child dosing equates to one quarter of a tablet per 3 kg. Nitazoxanide (hospital treatment) may be considered for recurrent treatment failures. Treat patients with severe disease, those who are immunocompromised and those with prosthetic vascular grafts. Common pathogens Salmonella enteritidis, Salmonella typhimurium Antibiotic treatment Salmonella enterocolitis First choice Ciprofoxacin Adult: 500 mg, twice daily, for three days Alternatives Co-trimoxazole Adult: 160+800 mg (two tablets), twice daily, for three days 19 Genito-urinary Bacterial vaginosis Management Women with bacterial vaginosis are often asymptomatic. It is not usually necessary to treat bacterial vaginosis unless symptoms are present or an invasive procedure is planned. Common pathogens Gardnerella vaginalis, Bacteroides, Peptostreptococci, Mobilunculus and others Antibiotic treatment Bacterial vaginosis First choice Metronidazole Adult: 400 mg, twice daily, for seven days, or 2 g, stat, if adherence to treatment is a concern, however, this is associated with a higher relapse rate Alternatives Ornidazole 500 mg, twice daily, for fve days or 1. A test of cure should be done fve weeks after initiation of treatment in pregnant women, if a non-standard treatment has been used. If symptoms are initially severe or signs and symptoms do not resolve (or worsen) after 24 to 48 hours, refer to hospital. A test of cure should be done fve weeks after initiation of treatment in pregnant women, if a non-standard treatment has been used or if symptoms do not resolve. As co-infection with chlamydia is very common, azithromycin is also routinely given. Women with severe pelvic infammatory disease and women who are pregnant require referral for specialist assessment. Ornidazole may be considered as an alternative, if metronidazole is not tolerated. Infants and children with pyelonephritis should be referred to hospital for treatment. Nitrofurantoin alone is not an appropriate choice for pyelonephritis as it fails to achieve tissue penetration. A urethral swab and frst void urine sample should be taken to exclude gonorrhoea and chlamydia (or use combination testing if available). Advise avoidance of unprotected sexual intercourse for seven days after treatment has been initiated, and for at least seven days after any sexual contacts have been treated, to avoid re-infection. Patients with symptoms persisting for more than two weeks, or with recurrence of symptoms, should be referred to a sexual health clinic or urologist. Common pathogens Urethritis not attributable to Neisseria gonorrhoeae or Chlamydia trachomatis is termed non-specifc urethritis and there may be a number of organisms responsible. Asymptomatic bacteriuria requires antibiotic treatment in women who are pregnant but not in elderly women or patients with long-term indwelling urinary catheters. However, urine culture is recommended in males, women who are pregnant, and those who fail to respond to empiric treatment within two days. Women who are pregnant should have repeat urine culture one to two weeks after completing treatment to ensure cure. Children aged over six months, without renal tract abnormalities, and who do not have acute pyelonephritis, may be treated with a short course (three days) of antibiotics. Management of infection guidance for primary care for consultation and local adaptation, 2012. Short versus standard duration oral antibiotic therapy for acute urinary tract infection in children. Such fevers do not all have an infectious cause, but they all require thorough investigation to rule out life-threatening conditions. This article summarizes the principles of diagnosis and management of postprocedure fevers for the emergency care provider. Infectious causes should be considered mainly for fever presenting later than 48 hours after surgery, whereas early postoperative fever is 2 most commonly attributed to noninfectious causes. Others have stated that nonin fectious causes appear to cause lower-temperature fevers (<38. Despite these claims, the cause of postprocedure fever is often not identified despite the rigorous efforts of clinicians. As with all medical diagnoses, a thorough history and physical examination should serve as the diagnostic starting point in ascertaining relevant information in terms of exposure to infectious pathogens. In addition, the timing of fever after a procedure can help differentiate potential causes. It is therefore useful to divide the time frame of postprocedure fever into 4 cat egories: immediate, acute, subacute, and delayed. Fevers that occur in the first 4 days after surgery are less likely to represent infectious complications than are fevers occurring on the fifth and subsequent days (Fig. Fever can also accompany the continuum of systemic inflammatory response, sepsis, severe sepsis, and septic shock (Table 2). In a prospective study of 81 patients with 2 idiopathic postoperative fever, Garibaldi and colleagues found that 80% of those with fever on the first postoperative day had no infection. However, a fever that begins on or after postprocedure day 5 is much more likely to represent a clinically significant infection, so appropriate diagnos tics to look for an infectious source may be useful. These tests can include laboratory investigations (blood culture, urine cultures, complete blood counts) and images (plain Fig. Percentage of postoperative fevers occurring on the indicated day following an oper ative procedure. Lines indicate the percentage of fevers occurring on each day attributable to the cause indicated. Definitions for sepsis and organ failure and guidelines for the use of innovative therapies in sepsis. These mediators increase capillary permeability and are central elements of 8 the inflammatory response and, thus, healing. The cytokines act directly on the ante rior hypothalamus and cause a release of prostaglandins, which mediate the febrile 5 response. The severity of the procedure, in terms of the extent of tissue trauma, can also influence the fever curve. For example, laparoscopic cholecystectomy is associated with fewer episodes 11 of postoperative fever than an open approach. Inflammation secondary to cytokine release is now thought to be the most com mon cause of immediate postprocedure fever. In the immediate postprocedure period, routine measurement of temperature fol lowed by a detailed laboratory or diagnostic workup is not warranted as long as the patient is hemodynamically stable. Diagnostic tests, such as blood or urine cultures, should not be ordered routinely during this period. A prospective triple-blind study involving 308 consecutive patients found that measuring postoperative body temperature was of limited value in the detection of infection after elective surgery for noninfectious 15 conditions. In the past, atelectasis was thought to be a common cause of postprocedure fever; however, numerous studies have shown that it is not clearly related to fever. Roberts 16 and colleagues evaluated 270 patients who had undergone elective abdominal sur gery, and reported the presence of fever in 40%. Atelectasis was associated 15 with neither the presence nor the severity of fever. Vermeulen and colleagues reviewed the records of 284 general surgery patients, who had 2282 temperatures taken. As a predictor of infection, a temperature of 38 C had sensitivity of only 37% and specificity of 80%, a likelihood ratio of a positive test of 1. Other common causes of immediate postprocedural fever include reactions to medication and transfusions, the presence of infection before the procedure, fulmi nant surgical-site infection, trauma, and adrenal insufficiency. These potentially life-threatening conditions mandate early diagnosis followed by prompt intervention. Presentations might occur particularly early, often within hours to 18 days of the initial procedure. The pathogen can be introduced from hematogenous spread from distant sites of 18,19 infection, minor trauma, or surgical incisions. Fournier gangrene can be caused by colorectal or genitourinary surgical intervention. Other potential sources include 20,21 intramuscular injections, odontogenic infections, or surgery. Commonly cultured organisms include Group A hemolytic streptococci, entero cocci, coagulase-negative staphylococci, Staphylococcus aureus, Staphylococcus 18 epidermidis, and clostridial species. In the emergency setting, particularly severe cases can present with signs of systemic inflammation (tachycardia and fever) and even with evidence of end-organ dysfunction (eg, confusion, hypotension). Early consultation with a surgical service is neces sary, given that definitive diagnosis and treatment both require operative interventions (debridement, collection samples for pathologic evaluation, and confirmatory diag 23 nosis). Prompt surgical consultation, in addition to administration of appropriate antibiotics 25,26 and intravascular volume resuscitation, is imperative. Broad antibiotic coverage should be initiated, covering gram-positive, gram-negative, and anaerobic organisms. Commonly used regimens include a penicillin (vancomycin in penicillin-allergic pa tients), clindamycin or metronidazole, and an aminoglycoside (or a third-generation 18 cephalosporin or aztreonam). Clinicians caring for these patients must remain watchful for signs of clinical deterioration. Patients who require large amounts of fluid resuscitation might develop pulmonary edema and subsequent respiratory failure requiring ventilatory support. When debride ment begins early in the course of illness, defined as less than 24 hours after presen 22,27 tation, the morbidity and mortality rates are significantly diminished. In general, fever associated with pulmonary embolism is of low grade (temperature rarely exceeding 38.

Occa sionally, patients can undergo prolonged remission after first recurrence and treatment with chemother apy and reoperation. To date, however, there is no evidence that patients with infratentorial ependymo mas benefit from adjuvant chemotherapy (Lefkowitz et al. Clinical this low-grade neoplasm consists of clustered glial nuclei in a trials are now being conducted to evaluate the possi fibrillary stroma composed of cell processes. The most common symptoms and signs are to radiotherapy or chemotherapy, but long-term dis nystagmus, headaches, and vomiting; cranial nerve ease control is usually poor (Packer et al. Occasionally tumors can have elements of subependy momas intermixed with more prominent classic ependymal elements; while the intermixture of the two is common, the preponderance of the ependymal el ements may alter the prognosis, which may approxi mate the fate of children with ependymomas. Treatment the treatment of choice for symptomatic tumors is surgical resection (Jooma et al. For patients with pure subependymomas, there is as yet little evi dence that adjuvant radiotherapy or chemotherapy are beneficial. There is also little experience in the treatment of subependymomas with chemotherapy at the time of disease recurrence. Less his tologic similarity to normal choroid plexus is found in the rarer choroid plexus carcinomas (Fig. Total surgical resection without additional therapy results in long-term disease control for children with choroid plexus papillomas and for some patients with carcinomas (Packer et al. The utility of adjuvant radiotherapy or chemotherapy for incompletely resected lesions, including carcino mas, has not been proved in a prospective clinical trial. Recently, however, Wolff and colleagues (1999) reported a retrospective analysis of 48 patients with choroid plexus carcinoma and total tumor resection, of whom one-half received postsurgical irradiation.

It is best to avoid stockpiling of supplies because they may be influenced by changes in temperatures symptoms checklist buy oxybutynin 5 mg overnight delivery.

But, if you want to rinse, use slightly soapy water and a large irrigating syringe or baster to flush out the pouch. Cleaning around the stoma as you change the pouch or skin barrier may cause slight bleeding. A straight razor should not be used to shave this area, if you must use a razor an electric is the best choice. Flatulence (Gas) Immediately after surgery, it may seem that you have excessive gas almost all the time. Skipping meals to avoid gas or discharge is unwise because your small intestine will be more active and more gas and watery discharge might result. The odor of ileal contents is not the same as that of a normal stool because the bacteria that cause food breakdown (and odor) in the colon are not present in the small intestine. If you have itching and a rash, they may prescribe topical medication such as Mycostatin powder or Kenalog spray. For deep pressure ulcers caused by a very tight belt, loosen or remove the belt and call your physician or ostomy nurse immediately, treatment is needed. Obstruction/Blockage There are occasions when the ileostomy does not function for short periods of time. You must quickly replace these electrolytes to avoid becoming ill from dehydration and mineral deficiency. Then replace fluids by taking one cup of sweetened, clear tea or one glass of orange juice followed the next hour by one cup of salty broth. Electrolyte Balance Electrolyte balance (especially potassium and sodium) is important. If the rectum has not been removed, one may also have this feeling and may pass mucus when sitting on the toilet. Do not submit to any procedures you think may be harmful such as taking a laxative, taking an enema through the stoma or rectum, or insertion of a rectal thermometer. Ask to have the following information listed on your chart: 1) type of ostomy or continent diversion 2) whether or not your rectum has been removed or is intact 3) details of your management routine and products used 4) procedures to be avoided (see above). Beginning a new job, moving to another city, marriage and having children are all examples of adapting to a new way of life. Having a positive outlook on life, patience and a sense of humor are keys to adjusting to any new situation. Talking to a trusted friend, nurse, clergy and certainly another person with an ostomy may help you work through those feelings. You can enjoy all activities such as travel, sporting events, eating at restaurants or whatever you enjoyed before. You may also worry about your pouch filling with gas and bulging under your clothing. Telling Others About Surgery You might be worried about how others will accept you and how your social role may be changed. Talking about your surgery in a natural way will dispel any misconceptions they might have. If you are considering marriage, discussions with your future spouse about life with an ileostomy and its effect on sex, children and family acceptance will help to alleviate misconceptions on the part of the spouse. Clothing and Appearance One does not need to purchase special clothing after ileostomy surgery, but some minor adjustments may be necessary for comfort and preference. The pressure of undergarments with elastic will not harm the stoma or prevent function of the bowel. A simple pouch cover adds comfort by absorbing perspiration and keeps the pouch from resting on the skin. If you do not like the pouch being next to your skin, you can cut an opening in your underwear and stitch around it. Here are a few simple guidelines about your diet: Eat slowly and thoroughly chew all solid foods. If a small serving gives you cramps or diarrhea, eliminate that food from temporarily and try it again in a few weeks. Dehydration and loss of electrolytes (salts and minerals) are possible if not enough fluids are consumed in a day. Increase your fluid intake and salt if perspiring heavily or you are in hot climates. Tomato juice and food dyes may change the usual color of ileostomy output as well. Additional dietary guidelines may be found in the Diet and Nutrition Guide published by the United Ostomy Associations of America. Returning to Work As your strength returns, you can go back to your regular activities. Still, persons who have ileostomies do heavy lifting, such as firemen, mechanics and truck drivers. As with all major surgery, it will take time for you to regain strength after your operation. Intimacy and Sexuality Sexual relationships and intimacy are important and fulfilling aspects of your life that should continue after ostomy surgery. Any sexuality concerns you have should be discussed openly between you and your partner. It is likely that your partner will have anxieties about sexual activities due to lack of information. An intimate relationship is one in which it matters how well two people can communicate. Your interest in sex will gradually return as your strength is regained and management issues are mastered. If the relationship grows and leads to intimacy, the partner needs to be told about the ostomy prior to a sexual experience. If you are healthy, the risk during childbirth appears to be no greater than for other mothers. For more information, the guide book Intimacy, Sexuality and an Ostomy is available from the United Ostomy Associations of America. Many physicians do not allow contact sports because of possible injury to the stoma from a severe blow or because the pouching system may slip. Indeed, people with ostomies are distance runners, weight lifters, skiers, swimmers and participate in most other types of athletics. Normal exposure to air or contact with soap and water will not harm the stoma and water does not enter the ostomy opening. Many people with ileostomies travel extensively including camping trips, cruises and air travel. Further problems might be avoided by having this information translated into the language or languages of the country(s) you are visiting. Before traveling abroad, get a list of the current English-speaking physicians in various foreign cities that charge a standard fee. It should be filled in your home state, since the prescription may not be valid elsewhere. You may think that your dreams have been shattered and may wonder if your child will be able to do the things that others do. Psychosocial Issues As your child begins to recover from ileostomy surgery, there are many ways you can be a source of strength and support. Too much sympathy, however, is not good and will take away a sense of independence. The changes in body image caused by the ileostomy may compound the stresses of adolescence. Your teenager may feel unattractive, rejected and different because of the ileostomy. If he or she is old enough, you will want to encourage independence in their ostomy care. An older child can get supplies together and learn steps of changing the pouch, until the whole process can be done alone. There are some changes that will occur in the beginning that will not happen later. You might pick up your child for a pouching change at home, then he or she can return to school. One youngster tells this story: he noticed that his pouch was leaking and had stained his trousers. In this way, he very wisely avoided embarrassment and then called home so that his mother could pick him up. You will find that your child can participate in sports, can go on overnight trips, to camp and do all activities enjoyed before. Discuss what can be done if any problems come up while your child is away from home. Cleaning up the bathroom after ileostomy care is important to maintaining family harmony. Parents find that a healthy child with an ileostomy can once again be a happy child. Planned educational sessions on self esteem, body image, hygiene, ostomy issues plus discussion sessions, craft projects, tours and sports are offered. If you are in a place where you cannot make contact with them, try to find a doctor or clinic specializing in ostomy care. Continent Diversion: any fecal or urinary diversion that avoids the need to wear an external collecting pouch. Diverticulitis: inflammation of the diverticula (little sacs on the colon); can cause abscess, scarring with stricture or perforation of the colon with peritonitis in severe cases. Enzyme: substance formed in animal and plant cells that start or speeds up specific chemical reactions. Familial polyposis requires regular medical supervision of all members of the family because of serious complications and strong tendency to malignancy. Fistula: an abnormal passage between two internal organs or from an internal organ to the surface of the body. Hernia (abdominal): the protrusion of an internal organ through the abdominal musculature; can occur around stomas. Obstruction: blockage of ileostomy indicated by partial or complete stoppage of ileal flow. Peristalsis: progressive waves of motion which occur without voluntary control to push waste material through the intestine. Revision: construction of a new stoma when the original one does not function well. Ulcerative Colitis: one form of inflammatory bowel disease in which ulcers form in the intestinal lining of the colon and rectum. Talk to your health care provider about which ones might be good options for you and to your health insurance provider about your coverage.
